I've been reading carefully in here and think I have a good understanding of the potential problems with the PSD. The truck has 52K miles on it. According to the Oasis report it had a turbo replaced in 2007, but that's it. Nothing else on the report.

I bought a scangauge II for the test-drive (it's being transferred from Nashville this week). During my test drive I plan to heat it up and have a look at the FCIM voltage and the ECT/EOT delta.

My question is -- and I know there's no guarantees -- with a very clean Oasis, and assuming the scangauge doesn't report any impending conditions, do you think I've got a good buy here?

Thanks in advance. Never owned a diesel and I'm a bit apprehensive. I used to work on cars when in was a kid. Haven't turned a wrench since that last head job on a Rambler classic 20 years ago. Think I can handle this?

I'd love to tell you you're getting a great buy here but there's no guarantee like you say.

Looks can be very deceiving with this particular truck. Thing is, and correct me if I'm wrong here someone, that the truck is out of warranty by date which means all repairs may not show up on oasis.

I'm not saying not to buy it just be very apprehensive and aware of the potential for serious problems. 52k is pretty low miles for this rig depending on original DOP...I know there are exceptions to the rule but it's questionable.

Definitely strike the best deal you can and if possible find another .org member near you that is willing to take some time to help scope it out. After all, we're all here for the same reason. Good luck

I've studied enough in here to know what to look for on the scan gauge. If I see a delta between ECT/EOT greater than 15 I'm going to insist that the dealership replace the oil cooler or I won't buy it. If the FCIM voltage doesn't look healthy I'll make them replace that as well.

If I buy it, first mod its getting will be a coolant filter to stop any potential damage to the oil cooler/ERG system.

I'm also going to take it to a Ford dealership and get the latest flash that sweeps the vanes on idle. And I'll give it the high idle mod as well.

Any other suggestions you guys can offer? Appreciate your advice, thanks in advance.

[QUOTE=7.34ever;3189501]Why not take the money from the coolant filter setup and put it towards an egr delete to eliminate that problem immediately? Just sayin...

From everything I've researched, it all starts with coolant (and casting sand) slowly plugging the oil cooler, resulting in higher oil temps. As a lovely side benefit, coolant flow is restricted to the EGR system which screws that system up too. The grand finale is losing head gaskets.

So to me, the first priority is stopping further damage from ocurring. Then I'll do an EGR delete, and if I get lucky, I won't have to replace the oil cooler - yet.
